60+ processes is a bit much, I'd think, unless you have a lot of programs that are told to start up with windows. You 'might' have some mal-ware that is doing stuff behind your back and taking up processor time.

There are special programs to look at this activity....you might take a look a Karen Kenworthy's Power Tools especially "Window Watcher" and "Snooper"

It also might just be settings that are performing regular tasks, like cache cleaning, and doing it too often and finding too much to do......so many different possibilities depending on how YOU use the machine.
